Print out this year's Glastonbury Festival line up and it's a boggling 15 pages of A4. Allow Newsbeat to guide you through and make sense of some of the hundreds of acts on offer.
Glastonbury festival takes place between 24-28 June in Somerset
People go to Glastonbury festival for all kinds of reasons. Some go to rename themselves Gandalf, sit in a canoe hoisted into a tree and shout magic spells through a mega-phone. And that's fine.
But there's also the small matter of hundreds of acts playing across more than 20 (official and unofficial) stages. A first glance at the line up can be almost as confusing as finding your tent so here's Newsbeat's tailored musical trails - depending on what you want to get out of your weekend.
THE HOTTEST NEW BANDS RIGHT NOW
Beyond some of the biggest selling artists in music gracing this year's Pyramid Stage lurks some of the hottest talent around. Alessi's Ark (Queen's Head) and Kap Bambino (Queen's Head) will kick things off on Thursday.
One's a fairytale telling teenager from London, the other two French dance nutcases who writhe on the floor.
Milo Cordell and Roobie Furze from The Big Pink
Northern Irish bods General Fiasco (John Peel, Friday) have just put pen to paper on their first record deal and count Snow Patrol's Gary Lightbody as a fan. First timers at Glastonbury The Virgins (John Peel, Friday) bring New York City indie sleaze and swagger. Meanwhile, much hyped duo The Big Pink (John Peel, Saturday) come grasping a wall of melodic shoe-gaze noise.
For those with a thirst for young blood Saturday afternoon sees an unmissable four band relay at the John Peel Tent: The Temper Trap, Hockey, Gaslight Anthem and Passion Pit. They'll be amongst the most talked about bands of the weekend.
Charming in opposing ways, ex-record company workers We Have Band (John Peel, Sunday) and Swedish teenage two piece First Aid Kit (Park Stage, Sunday) are soft introductions to the final day.
Independent acoustic songstress Kate Walsh (Acoustic, Sunday) recently knocked Take That off the top of the iTunes albums chart - in other words, worth keeping an eye on.
A TRIP DOWN MEMORY LANE
Sunday afternoon on Pilton Farm's hallowed Pyramid stage looks like a bowls club membership registration. Status Quo, Tony Christie and Tom Jones might all be of the original Glasto generation, but there's nothing wrong with some nostalgic rocking.
Others who may need a hand getting around the site but also may provide some warming highlights include The Specials (Pyramid, Friday) back together after a 28 year hiatus.
Bruce Springsteen headlines Saturday night's Pyramid stage
There's no denying Neil Young (Pyramid, Friday) will provide folky-thrills for anyone over the age of 40.
One gent with plenty of energy left is 'The Boss'. Bruce Springsteen will show the youngsters how it's done by closing the Pyramid Stage on Saturday night. Meanwhile, Rolf Harris (Jazz World, Saturday), Hugh Cornwall (Acoustic Stage, Friday) and Ray Davis (Acoustic Stage, Friday) are masters of their particular, and peculiar, trades.
DANCE THE WEEKEND AWAY
Creamfields might be spiritual home of dance in the UK come festival season but Glastonbury puts up a fair fight when it comes to beats. Between the Glade, Dance stages and Wine Bar, which pumps out 80s disco all weekend, the Eavis' have it covered.
Skream and Benga (West Dance, Friday) are the first to bring it. Skream, aka Oliver Jones was responsible for the re-tooling of La Roux's In For The Kill - therefore, expect a set of dub-goodness.
Deadmau5 aka Joel Zimmerman plays East Dance on Saturday
Strictly speaking not dance but Animal Collective's (Park Stage, Friday) woozy-beat layering and luminous stage show will have the throngs swaying.
Come Saturday turning the voltage up will be Pendulum (Other stage), Heartbreak (East Dance) and Canadian producer Joel Zimmerman Deadmau5 (East Dance) who is likely to appear wearing a giant disco ball mouse head. Not to be missed.
Sunday - if your wellies haven't worn through yet - sees well connected Londoner's Filthy Dukes (West Dance) play fist clenching electro before the daddies bring the weekend to a shuddering close. The Prodigy (Other Stage, Sunday) overpowered the sound system at Radio 1's Big Weekend just a few weeks back with their confrontational show. Time for round two.
FIND THE GLASTONBURY 'MOMENTS'
Dictionary definition: A 'Glastonbury moment' - an anthem where all those who didn't get a ticket sat at home watching on TV release a collective sigh and those on site jump/cry/lose it.
Steadily heading towards the top of the charts, Little Boots' (John Peel, Friday) New In Town could be the first major sing-a-long of the weekend. Friendly Fires (Other Stage, Friday) will almost inevitably bring their South American dance troop for Jump In The Pool.
Just Dance in a field of mud plus Lady Gaga's (Other Stage, Friday) very un-festival outfits should combine to hilarious effect.
Dizzee Rascal will play the Pyramid Stage on Saturday
We're 99% sure Dizzee Rascal's Bonkers (Pyramid Stage, Saturday) will see Somerset go collectively barmy. Bruce Springsteen's (Pyramid Stage, Saturday) Born To Run will be a flag-waving, midnight delight.
Come final day, due to tiredness or otherwise, Yeah Yeah Yeahs' (Other Stage, Sunday) Maps could evoke a few tears. The Noisettes' (John Peel, Sunday) Don't Upset The Rhythm (Go Baby Go), Black Eyed Peas' (Jazz World, Sunday) Boom Boom Pow and Calvin Harris' (East Dance, Sunday) I'm Not Alone are guaranteed crowd bouncers.
And finally, the big one, Blur (Pyramid Stage, Sunday). With a raft of huge songs to choose from, the mighty Song 2 is built for closing a festival as historic as Glastonbury.
THE RANDOM GENERATOR
Spinal Tap will play the Pyramid Stage on Saturday
Finally, only Emily and Michael Eavis really know just who everyone is playing Glastonbury.
If you're not bothered catching the main players and just want to stumble on something funny with a spicy cider our recommendations are as follows: Bjorn Again (Pyramid, Friday), Spinal Tap (Pyramid, Saturday), Warsaw Village Band (Jazz World, Saturday), Penguin Café Orchestra (Acoustic Stage, Sunday), Jodie Harsh (West Dance, Sunday) and Will Young (Avalon, Sunday).
